Journal of oral biosciences·2026

Area of Science:

  • Biomineralization and developmental biology.
  • Focus on extracellular matrix (ECM) and basement membrane (BM) roles in tissue formation.

Background:

  • Mineralized tissues uniquely utilize proteins to organize calcium and phosphate ions.
  • Tooth development involves complex interactions between neural crest cells and the oral environment.
  • Basement membrane components are critical regulators of epithelial-mesenchymal cell interactions during development.

Purpose of the Study:

  • To review the function of the extracellular matrix, specifically the basement membrane and enamel matrix.
  • To elucidate the molecular mechanisms underlying tooth morphogenesis.
  • To highlight the importance of understanding protein expression and distribution in mineralized tissue formation.

Main Methods:

  • Review of existing literature on tooth development and extracellular matrix.

  • Analysis of the roles of specific matrix proteins like laminin and collagen IV.
  • Discussion of changes in ECM composition during tooth morphogenesis.

    • Main Results:

    • Extracellular matrix and basement membrane components are vital for cell proliferation and differentiation.
    • Basement membrane components (laminin, collagen IV) initially support dental epithelium.
    • The basement membrane structure between dental epithelium and mesenchyme degrades during later stages of tooth development.

    Conclusions:

    • Precise knowledge of matrix protein expression and distribution is essential for understanding mineralized tissue function.
    • The basement membrane and enamel matrix play dynamic, yet not fully understood, roles in tooth morphogenesis.
    • Further research is needed to clarify the molecular mechanisms of ECM and BM in tooth development and associated diseases.
